Description Bastien Nocera 2012-01-25 10:48:03 UTC 
<poojig> the kernel is sending the proper ABS_MISC event, but for some reason its value isn't being saved to the device state for devices which aren't protocol 5 (e.g. Cintiq and Intuos)

After trying out a few things, I'm not sure where the problem lies. My best guess at the moment is that its a kernel bug, but the evidence is sketchy. Its the only thing that's managed to fix the bug on the one system I have which shows similar behavior. Unfortunately its "buggy" kernel was built from an unknown commit sometime between 3.2.0-rc3 and 3.2.0-rc4 and its image is incompatible with my other boxes...

Did some more looking into this issue and discovered the root cause was an incorrect prerequisite check by wcmUpdateSerial. Patch sent to linuxwacom-devel:
